FEATURES

RADIATOR DEIGN

For safety valve over 350 DegreeC&comma; the radiator strcuture will be applied to suit high temperature conditions&comma; the radaitor will help to disperse heating and protect the spring form overheating circumstances so as to ensure the stability of spring&period;

HIGH PERFORMANCE SPRING

Only high grade spring is selected for operation for safety valve&comma; the spring has been gone through strictly test including physical and chemical analysis so as to ensure the best stablity and safety for operation&period;

FINE STEM PROCESSION

The stem was processed by CNC machine to give 100&percnt; vertical so as to make sure the smoothly opening and blowing of the safety valves&period;

DOUBLE ADJUST TING

Double adjusting ring are used for blow down adjustment&comma; we give fine procession of adjusdting ring to give smoothly adjusting for safety valve&period;

NOZZLE AND DISC

The surface of both disc and nozzle seat is deposited with hard alloy of Stellite&comma; and the excellent surface treatment by precision machining and lapping ensure the tightness and stable performance during the operation&period;
